Distribution: Conectiva Linux Snapshot version
Hardware Environment: AMD Athlon(tm) 64 Processor 3000+ (32bit mode)
Software Environment: samba 3.0.3pre2, glibc-2.3.3 (client). Server is win2k,
service pack status unknown at the moment, I'll check later.
Problem Description:

Can't mount a windows 2000 share. smbclient accesses it without problems. Upon
mounting and trying to access it, I get an error: "invalid slot".

strace part:
lstat64("/mnt/win", 0x805b0d4)          = -1 EBADSLT (Invalid slot)

I also tried with cifs

Steps to reproduce:

[root@pandora root]# mount -t smbfs //win2k/nbt /mnt/win -o username=andreas
added interface ip=10.0.17.30 bcast=10.0.23.255 nmask=255.255.248.0
Got a positive name query response from 10.0.20.215 ( 10.0.20.215 )
Password: 
[root@pandora root]# mount|grep smbfs
//win2k/nbt on /mnt/win type smbfs (0)
[root@pandora root]# ls -la /mnt/win
ls: /mnt/win: Invalid slot
